ObjectivesThe aim of this study is to examine the patterns of failure after extended surgical staging and postoperative vaginal vault brachytherapy as the only adjuvant treatment in high-risk surgical Stage I patients with endometrial carcinoma.MethodsThe records of all patients with endometrial carcinoma (adenocarcinoma or adenosquamous) receiving vaginal vault brachytherapy as the only adjuvant treatment from January 1989 to December 1997 were examined. A total of 489 patients were found. Of these, 133 had extended surgical staging. The study group consists of 77 surgical Stage I patients with Substages IBG3 and any grade IC. Recurrences were recorded as in the vagina, pelvis, or distant.ResultsThe mean follow-up interval was 45 months (range 14 to 96 months). Eleven patients had recurrence (14%). Median time to recurrence was 15 months (range 6 to 56 months). Recurrences occurred in the vagina in 7, pelvis in 1, and distantly in 3 patients. Five of 7 vaginal recurrences occurred within 2 years. All patients with distant recurrence died from disease. One patient with pelvic recurrence is alive with disease. Only 1 patient with vaginal recurrence died from disease. Six patients with isolated recurrences in the vagina were successfully treated with radiotherapy with or without local excision. All 6 have no evidence of disease at follow-up (median survival 29 months, range 20 to 71 months).ConclusionsThe vagina remains the most common site of recurrence for high-risk surgical Stage I patients treated with postoperative vaginal vault brachytherapy. Close follow-up in the first 2 years is essential to detect isolated vaginal recurrences. These are amenable to salvage treatment with good disease-free survival.Copyright 2000 Academic Press.
